  The consumable anode process allows the electrochemical preparation of arylzinc compounds in the presence of cobalt chloride as catalyst in a mixed solvent acetonitrile/pyridine (9:1). Conjugate addition of these organometallic reagents to olefins is also obtained in good yields via a new method using CoBr2(2,2′-bipyridine)2 as catalyst.

  An efficient method for the synthesis of ester-containing indium homoenolate via a direct insertion of indium into beta-halo ester in the presence of CuI/LiCl was described. The synthetic utility of the indium homoenolate was demonstrated by palladium-catalyzed cross-coupling with aryl halides in DMA with wide functional group compatibility.

  Light-mediated Halogen-Atom Transfer (XAT) has become a significant methodology in contemporary synthesis. Unlike α-aminoalkyl and silyl radicals, ligated boryl radicals (LBRs) have not been extensively explored as halogen atom abstractors. In this study, we introduce NHC-ligated boranes as optimal radical chain carriers for the intermolecular reductive radical hydroalkylation and hydroarylation of

  光介导卤素原子转移（XAT）已成为当代合成的重要方法。与α-氨基烷基和甲硅烷基不同，连接硼基（LBR）作为卤素原子抽象剂尚未得到广泛研究。在本研究中，我们引入 NHC 连接的硼烷作为最佳自由基链载体，通过直接 UV-A 光照射进行缺电子烯烃的分子间还原自由基加氢烷基化和加氢芳基化。 DFT 分析使我们能够合理化 NHC 配体在促进有效链增长方面的关键作用。
